Animated Model Import

I have done an easy animated model with blender, a cube with 2 frame, no armature, only object. In blender the animaion works perfectly but when I import blender file with JMonkey all is imported but not the animation, I have the j3o file without animation.I don’t understand the reason.

Thank you for any help

the belnder importer is not stable yet

you need to use bone animations

Ok thank you
